| 摘 要： | 针对虚拟景区场景大、对象多的特点,提出了一种层次碰撞检测方法。首先运用空间剖分法过滤掉远处不可能碰撞的对象,然后再通过构建碰撞检测空间,剔除掉待测运动对象附近暂时不可能碰撞的对象,最后再运用S-AABB层次包围盒法根据每个对象的具体精度要求进行精确碰撞检测。该碰撞检测方法在满足实际精度要求的前提下,降低了碰撞检测次数和复杂度,提高了实时性,是一种针对虚拟场景高效快速的碰撞检测方法。

| Abstract: | Due to the big scene and massive objects of the virtual scenic spot,this thesis present a method of hierarchical collision detection.The method firstly use the spatial partition to filter the far-away objects.Then,by constructing the space of collision detection,filter the vicinal object that will not have a collision with the moving object.And at last,using the method of S-AABB hierarchical bounding-box for accurate collision detection according to the requested precision level.The method used in this thes... |
